LMU-1300 Training Guide
Revision & Date
0.8–09/22/2020
for the exact measurements and specifications of the LMU-
1300™.
Typical installations will place the LMU under the vehicle dash board, or in the trunk. Make sure you can
get access to the unit afterwards as under some circumstances it may be necessary to add additional
wiring or connections to the LMU.
Protection from Hear
It is best not to place the LMU unit in an unusually warm location such as directly near heater vents, near
hot engine components or in direct sunlight. The maximum temperature that can be tolerated by the
LMU is described in the LMU
Visibility of Diagnostic LEDs
Status LED lights on the front of the LMU unit can provide valuable information about the operation of
the LMU. When feasible, attempt to install the LMU in such a way that these lights can be seen with
reasonable ease.
You may find it useful to be able to view the LEDs periodically to make sure that the LMU is operating
properly. If at any time you should encounter a problem with the LMU, you may need to read the LEDs in
order to troubleshoot the problem. If you cannot fix the LMU yourself, you will need to provide the LED
information to CalAmp customer support.
For information about how to interpret the LEDs, see the Status LED Behavior section.
Cable Length
Do not cut cables. Instead, coil any excess length, making sure not to crimp or flatten any cable.
Moisture and Weather Protection
The LMU unit must be located where it will not be exposed to moisture or water. In a typical installation
inside a vehicle this is not commonly thought to be a concern; however, it might be best to avoid locating
the LMU below a car’s cup holders, or where rain might easily splash into the compartment when a door
is opened.
Preventing Accidental of Unauthorized Modification
If you anticipate that fleet drivers or others might interfere with the LMUs once they are installed, take
steps to be sure that it is not easy to remove the LMU from its power source, or disrupt internal antenna
interference.
Two common methods are the use of Tamper Proof Sealant or creation of PEG Script to detect power loss
or GPS antenna disconnections.
